This item is currently not available.


These Coreloft™ insulated pants are designed to keep you warm on the coldest days, or to be used as an extra outer layer during low activity moments in the mountains.


Arc’teryx-developed Coreloft™ insulation has a very high warmth-to-weight ratio, meaning it delivers great warmth for very little weight and low profile volume. The resilient structure of the insulation resists compacting, so it can be repeatedly stored and returned to full loft. The outer fabric on the Atom LT Pant is weather-resistant, enabling it to function as an outer layer. Full side zips provide ventilation as desired and open pant legs wide when dressing over equipment.
